Embodiment
Also with reference to accompanying drawing, the utility model is further described below in conjunction with embodiment.
The Reference numeral related in accompanying drawing and ingredient as follows:
1. turn core pipe 2. turns of core sleeve 3. infrared filtering plate racks
4. infrared fileter 5. section O-ring seal 6.CMOS photo-sensitive cell
7.CMOS circuit board 8. turns of core sleeve rubber ring 9. right casings
10. the left outside shell of grating 11. optical focus pipe 12.

16. horizontal concrete chute 17. turns core front end gabarit 18. shell interlayer breach
19. right casing spacing block set 20. turns core sleeve spacing block set 21. turns core pipe external thread front ends.
As shown in Figures 1 and 2, CMOS photo-sensitive cell (6) is fixed on circuit board (7) front end, infrared filtering plate rack (3) internal placement infrared fileter (4) and section O-ring seal (5), two little bars of infrared filtering plate rack (3) rear side are inserted two apertures corresponding to cmos circuit plate (7) front end, infrared filtering plate rack (3) and cmos circuit plate (7) are fixed together the fixing not rotatable cmos component of formation one.Then this assembly is inserted from rear side and turn core pipe (1), the horizontal ledge of infrared filtering plate rack (3) (15) is made to cut in the horizontal concrete chute (16) turning core pipe (1) middle part, place extruding bung flange afterwards at cmos circuit plate (7) again, namely complete cmos device fixing what turn in core pipe (1).
In accompanying drawing 1-2, turn core pipe (1) center section and contain and turn core pipe external thread (14), the shape turning core pipe front end gabarit (17) is straight trough mouth.Turn that core pipe (1) is outside nestedly turns core sleeve (2), turn core sleeve (2) leading inside and contain and turn core sleeve internal thread (13), periphery is nested with and turns core sleeve rubber ring (8), increases friction and is convenient to user's rotary dial.From turning core sleeve (2) rear, the core pipe (1) that turns of built-in good cmos component rotates into that to turn core sleeve (2) inner, when turn core pipe (1) front end screw out turn core sleeve (2) and turn core sleeve (2) rear side to turn core sleeve spacing block set (20) present position be horizontal level time, namely, time as shown in Figure 3, stop screwing in.Turn core pipe (1) by what combine and turn core sleeve (2) and put into right casing (9), notice that making to turn core pipe front end gabarit (17) correctly puts into shell interlayer breach (18), places pattern as shown in Figure 2.
As in accompanying drawing 1-3, housing parts is divided into left outside shell (12) and right casing (9), and shell both sides all have window, inner containing interlayer, containing rectangular enclosure interlayer breach (18) on interlayer.Turning core pipe (1) front end is optical focus pipe (11), and it is fixed on shell by other devices of video ear examining mirror, and optical focus pipe (11) inside comprises other beam condensing unit such as eyeglass and grating (10).Turn core pipe (1) when what combine and turn after core sleeve (2) puts into right casing (9), close left outside shell (12), then the edge of opening press-in of outer casing back turns the annular groove of core sleeve (2) rear end, fixed by the front and back position turning core sleeve (2) by interlayer and open rearward end edge, now turn core pipe (1), the turn turning axle of core sleeve (2) and cmos component central shaft is all on the optical axis of optical focus pipe (11).
As in accompanying drawing 1-3, when down stirring the rubber ring in right casing (9) window and making its dextrorotation, by turning core pipe (1) and turning core sleeve (2) internal and external threads gearing, then turning core pipe (1) should be left-handed, but owing to turning core pipe front end gabarit (17) for the straight trough degree of lip-rounding, shell interlayer breach (18) is rectangle simultaneously, its gap width and the width and the height that are highly a bit larger tham aforementioned straight trough mouth, therefore shell interlayer breach (18) stops that to turn core pipe (1) left-handed, therefore turn core pipe (1) and can only move backward, cmos device is driven to move backward, after a mobile segment distance, the spacing block set (20) turned in core sleeve (2) turns to right casing spacing block set (19) place, now rotate and be locked, anti-spline core pipe (1) is excessively mobile backward and back-out turns core sleeve (2), in like manner, when down stirring the rubber ring in left outside shell (12) window and making it left-handed, cmos component moves forward, and its spacing locking function is determined by the shell interlayer in the middle of shell, when turning core pipe external thread front end (21) and encountering shell interlayer, forward movement stops.These two steps can realize CMOS camera moving forward and backward on optical axis, the mechanical focusing function that completing user controls.
In Fig. 1-3, turn core pipe external thread (14) for two helical pitch right-hand threads, the specification size that the two helical pitches turning core sleeve (2) front end turn core sleeve internal thread (13) is consistent with turning core pipe external thread (14).Turn core sleeve (2) rear side containing a projection turn core sleeve spacing block set (20), right casing (9) inner back side contains right casing spacing block set (19).Turn core pipe external thread (14) by setting after accurate Calculation and turn the specification of core sleeve internal thread (13), and turn core sleeve (2) and right casing spacing block set (19), turn the position of core sleeve spacing block set (20), after being decorated with scale according to the anglec of rotation turning core sleeve (2) again on shell and rubber ring with the relation turning the movable distance of core pipe (1) again, user can be made accurately to control the displacement of cmos element on optical axis.
The utility model specific operation process is as follows: when adjusting the focal length of CMOS photosensory assembly and thing to be captured, imaging figure in first view screen, then in shell middle window, slowly turn the rubber ring (8) of core sleeve (2) up and down, fix owing to turning core sleeve (2) front and back position, its front end turns core sleeve internal thread (13) and turns core pipe external thread (14) and interact when it is turned, make to turn core movable on axis, be fixed on the CMOS inductive component turning core inner to move thereupon, when CMOS sensing element reaches optimal imaging focal length point, imaging figure on screen is also clear, adjustment can be stopped, start to carry out shooting to observe.
Other case study on implementation of the present utility model comprises: change the type and the specification size that turn core pipe external thread (14) and turn core sleeve internal thread (13), change and turn core sleeve (2), right casing spacing block set (19) and turn the position of core sleeve spacing block set (20), change the shape of shell interlayer breach (18) and turn the shape of core pipe front end gabarit (17), or spacing block set is set on left outside shell (12) and does not use interlayer to perform locking function during forward movement, but its core content is all by fixedly turning core sleeve (2) front and back position, make to turn core pipe (1) by the interlayer in shell to rotate on optical axis, turn core sleeve (2) again thus make fixing turning core pipe (1) and certain scope can only be moved forward and backward on optical axis containing cmos component, thus be convenient to user can the imaging focal length of fine adjustment cmos element.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvement and supplement, these improve and supplement and also should be considered as protection domain of the present utility model.
